Answer :
700*6=4,200
*4,200 as an estimate.
---------------------------
6*(758)
=6(700+50+8)
=4,200+300+48
=4,200+348
=4,548
*4,200 as an estimate.
---------------------------
6*(758)
=6(700+50+8)
=4,200+300+48
=4,200+348
=4,548
Estimation: 760 × 10
The 760 came from the 8. The 8 had round up the 5 to a 6. The 10 came from were because the 6 was higher than 5, it rounds up to 10.
Product: If you mean the estimating number, then 760 × 10 = 7,600 or if you mean the original number, then 758 × 6 = 4,548.
